ROLLING CORRUGATED METAL.

A specification of Lettere Patent No. 26,607, dated December 27,1859.

To all whom it may concern:

Be it known that I, RICHARD MONTGOM- ERY, of the city, county, and State of New York, have invented a certain new and useful improvement in machines for` corrugating, smoothing, and forming metallic arched surfaces from pla-ne sheets or plates of metal at one heat; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification, in which# j Figure 1, represents a front view of the machine. Fig. 2, represents a rear view of the machine, showing the sweeping roll H. Fig. 3, represents a longitudinal section through the holding and smoothing rolls, and a similar section through the` frame which supports the corrugating rolls, and Fig. 4, represents a section on line A, B, Fig. l, showing the relative position of the carriage e, holding and smoothing rolls G,

G, and sweeping or arch forming roll H.

A, A, represent the frame which supports the corrugating rolls E, E, and D, D, the frame which supports the holding and smoothing rolls G, G, together with the arched forming roll H. Both frames are securely fastened to a base C.

The rolls E, E, are corrugated lengthwise, and turn on journals E', E. Through the cap piece B, pass adjusting screws B', B', for the purpose of forcing the upper roll E, down against or toward the lower roll E,the journals of the upper roll E, being mounted in boxes or bearings a, as, which slide up and down in frame A.

The holding and' smoothing rolls, G, G, are corrugated with parallel corrugations running around the rolls as fully shown in Fig. 1-and are mounted on journals G', G which turn in pro er bearings in frame D, D, the upper roll eing adjusted by means of screws b. The rolls G, G, aregeared to ether by ears F, F. l

o the en of the journal of the lower corrugating roll E, is attached a socket piece K, while the journal E, is bored out so as to admit of the end of the journal of the lower roll G, being inserted therein so that a pin or bolt can be passed through the cap or socket piece K, and both journals, whereby the power which is applied to drive the corrugating rolls E, E, will also, and at the same time give motion to the holding or smoothing rolls G, "GQ Aclutch couldibe i used `to connect the lowerrolls G, and E, so j that by means of `a lever, therolls G,I

could be thrown `out of action at anytime.

Supporting rails UZ, d, are attached tothe front of the frame D, D, upon whichyruns` the wheels z', c', of a carriage e. The` car` riage e, has side` guides g, g, while the` top of the carriage is so arranged` as respects the rolls G, G, that its top isalittle below the top of the corrugations on thebottom f roll G. The ends of the supportingrailsdys d, are providedwith stopsf, f. .j j The operation is as follows, viz: The

heated, is fedin side-wise between the corrugating rolls E, E, and inpassing through,"`

it is corrugated, when it is turned and passed back over the top holding `roll G, onto the` carriage c, and between the sides g, g-then j forward so as to be caughtbetween the hold` ing rolls G, G, so that the corrugations j the sheet or plate will fit into the corrugations in the rolls G, G, whereby the sheet or plate is held firm and is also forced through between the rolls G, G, and up over the corrugated forming roll H, (as seen at L, Fig.

4,) which has its bearings in that part of the frame D, marked D.

The rolls G, are not intended to work so close together as to increase the corruga` tions, but only to smooth the corrugations,

and to hold the sheet or plate firm and even while it is being curved or bent into the desired form bythe roll`H.` The roll H, can

be set to give any desiredcurve to the plate by means of the screws c, c. i

By the above combination and arrange` l, g

ment of mechanism, I am able Erst to corrugate` the plate sidewise, then smooth the f corrugations andalsogive the `sheet or plate an arched form in thedirection of the cor-` i rugations by one heat of the iron. y

In corrugating iron, it isfound: that the outer surface is somewhat cracked` or scaled up by the operation, hence it becomes necessary to pass `the corrugated plate or sheet 1 between a set of smoothing or pressing `rolls for the purpose of forcing or pressin back` the slight scales or cracks on the sur ace fof the metal so that when `in use the surface will be smooth and even.` `'Ihisis effected@` by my machine, at the `Sametime the" sheet" 1s being curved and immediately after ,1t` has been corrugated. y j i 1` The carriage e, can be run back` and forth `io` i sheet to be corrugated having been properly i what I claim and desire to secure by Letters Patent, is:-

'Ihe combination and relative arrangement of the corrugating rolls E, E, With the holding and smoothing rolls G, G, forming roll H, and carriage e, operating in relation to each as and for the purposes set forth.

RICHARD MONTGOMERY.
